Hello,
your software Logi Options+ is useless if i can't swap left and right button just for the Logitech mouse. I use two mice as needed, one on the left and one on the right. Your software will only change the general settings in windows so that both mice can only be used with the same primary button. Your old software SetPoint was able to set each mouse separately, but it no longer recognizes the M325s mouse.
